Work w/nutritionist: I'm not sure what "everything" entails, but the source of your difficulty may be found in the type of foods you eat. A calorie is not just a calorie -- it's information for your body and the metabolic systems that keep it going. You could work with an integrative medicine doctor and a nutritionist to look for possible food sensitivities, and also review your exercise and sleep routines.

Weight loss: One of the most difficult things to do is lose weight and keep it off. If you had a physical exam and blood work that showed no abnormalities the plan to lose weight starts out simple and straightforward. First you need to pay attention to the type and quantity of food. Lower your fat and carbohydrate intake. Decrease portion size. Drink lots of water. Add some exercise start by walking.

Family practice : You probably have metabolic syndrome. Your Insulin level should be checked. If greater than 10 it means that you are not getting your food into muscle cells to burn it off. Your body senses it needs more Insulin so produces an abnormal level of insulin. You become pre diabetic. You need to eat 70-100 grams of protein per day. Then get followed up.

Complex situation: For a female is even worse. Here is my take. Eat a total of 1, 200 calories a day in 6 divided small meals. Good carbs( as much spinach, lettuces, broccoli as you want), bake fish, meat and chicken. Increase your metabolism by a program of weight lifting exercise(muscle it's the most met. Active organ) alternating with lots of aerobic exercises. Try p90x program. Consult your doctor before.
